this plood rogram is about retinal blood vessel extraction in an quality and to improve performance by means of matched fillters and first order differntial gausian function.

the source code for the JPEG encoder in MATLAB language

Newton-Raphson method for all real roots of the polynomial 计算多项式实根的Newton-Raphson算法源代码(nonlinear fitting)

介绍了m 序列和Gold 序列的原理、性能和构造方法，接着在MATLAB 中用M 语言编程实现它们的产生和分析。(Describes the m-sequence and Gold sequence of principle, performance and construction methods, and then using M language in MATLAB programming their generation and analysis.)

用程序写的按钮之类的，我也没搞懂，不是直接添加GUI按钮(oh,it is a )

说明：  对原有修正PRI变换进行改进，将分散在真实PRI箱附近几个箱中的到达时间差值累加起来，提高检测性能(PRI transform the original amendment to improve, will be scattered around a few boxes in the real PRI box add up to the arrival time difference and improve the detection performance)

matlab环境中调用R语言命令和库。文件中附带简单安装步骤和matlab和R混合编程模板。方便matlab用户调用R语言的库。(call the R language commands and libraries matlab environment. File included simple installation steps and matlab mixed programming templates and R. Matlab convenient user calls the R language library.)

说明：  此matlab代码利用求解线性方程组的方法，实现了高斯二维曲面拟合（附数学原理PDF文档）(This matlab code use the method of solving linear equations to achieve gaussian two-dimensional surface fitting)

利用matlab的sedumi工具完成锥优化求解(Use tools to complete the matlab sedumi cone optimization solution)
